UIImages with alpha were ending up with garbage pixels in background (random memory values). Need to initialize matrix pixels before drawing UIImage with alpha on it.
Note: didn’t fix Grayscale image with alpha stripping alpha in UIImage -> Mat conversion.

Root cause: when calling imread to read the pgm file, when returning with success reading file, the destructor will free the resource which used by memcpy, but in the code, the resource calculation was not correct, therefore, it will cause memory corruption during resource free.
